What we fix on dishwashers

  • Won’t drain: blocked drain pump, clogged filter, bad drain solenoid. This is one of the most common calls we take
  • Dishes not clean: clogged spray arm, wash pump failure, water not hot enough
  • Leaking: door gasket, worn pump seal, inlet valve
  • Won’t start: door latch, control panel, thermal fuse
  • Won’t fill: inlet valve, stuck float, water supply
  • Loud running: wash arm bearing, chopper blade, drain pump
  • Door won’t latch: latch assembly, hinge spring
  • Error codes: E1, E4, F8, i30, and the rest, on every brand

A pump and sump leak, on camera

The base of a Whirlpool-family machine (Whirlpool, KitchenAid, Maytag), where the circulation pump, sump, and diverter sit. A worn pump seal, a cracked sump, or a bad diverter lets water past and onto your floor.

Try these before you call

A short list worth running first:

  • Power and latch. Confirm the door clicks fully shut and the breaker did not trip. A half-latched door is a common “won’t start” cause.
  • Delay start. Some models default to a delay cycle after a power blip. Check the panel before you assume the machine is dead.
  • Filter. Most machines built after 2010 have a twist-out filter at the bottom of the tub. A clogged one causes standing water and weak cleaning. Rinse it under the tap and reinstall.
  • Drain hose. If the machine was moved recently, or someone worked under the sink, confirm the drain hose still has its high loop or air gap at the cabinet.

If none of that fixes it, stop. The rest means pulling the machine and testing parts.

What the actual repair takes

The failures above (worn pump seal, dead heating element, bad board, cracked sump) all live inside the machine. Diagnosing them right means metering components, tracing the code to the actual part, and ordering brand-specific parts. Bosch, LG, and Samsung in particular use their own connectors and calibration steps that are not in the general guides. Guess wrong and you get a worse failure or a flooded cabinet.

We test, diagnose, and repair after the on-site diagnosis when we have the part on hand, and we get people on the schedule fast, often same or next day.

Ready to fix it?

For an accepted dishwasher brand, call (925) 999-4095 or schedule a visit. Tell us the brand, model, and symptom so the job record is accurate. We do not service Bosch, LG, Samsung, KitchenAid, Whirlpool, or Jenn-Air dishwashers. The $99 visit is credited to an approved repair.

Straight answer

The dishwashers we do not take.

We do not repair dishwashers from LG, Samsung, Bosch, KitchenAid, Whirlpool, or Jenn-Air. Any model, any year.

It is not a knock on the machines. It is the parts pricing. What a circulation pump, a control board, or a touch panel costs on one of these, set against what the dishwasher sold for new, turns the repair into a bad buy for you more often than not. We would rather tell you that here than charge you $99 to say it in your kitchen.

Everything else from these brands we still fix: refrigerators, ranges, ovens, cooktops, washers, and dryers. We repair dishwashers from every other brand.

  • Serviced: Fisher & Paykel, Miele, Cove, Asko. We also service every other residential and commercial brand.
  • Not serviced: LG, Samsung, Bosch, KitchenAid, Whirlpool, Jenn-Air dishwashers
  • Still serviced on those brands: refrigerators, ranges, ovens, cooktops, washers, dryers

FAQ

Common questions.

Why won't my dishwasher drain?
Most often a clogged filter or a blocked drain pump. Pull the twist-out filter at the bottom of the tub and rinse it. If there is still standing water after that, the drain pump or solenoid needs a meter test. We pin it down during the on-site diagnosis.
Why is my dishwasher leaking?
Usually the door gasket, a worn pump seal, or the inlet valve. Water pooling under the machine points at a pump or sump leak. Finding the source means pulling the unit and testing internals, so it is not something to probe blind. We track it down for you.
Why won't my dishwasher start?
Check the latch first, the machine will not run unless the door clicks fully shut. Then check whether a delay-start kicked in after a power blip. If both are fine and the panel is dead, it is likely a thermal fuse or the control board, and those need proper diagnosis before anything gets replaced.
Why aren't my dishes getting clean?
Usually a clogged spray arm, a wash pump issue, or water not reaching temperature. Rinse the filter and confirm the spray arms spin freely. If dishes still come out dirty, the wash pump or heating element probably needs testing.
What do the error codes mean?
Codes like E1, E4, F8, and i30 each flag a system, drainage, water intake, temperature, flood protection. They narrow the search but confirming the failed part takes a meter. We read codes across every major brand.
